This is a factory magazine for the Rock Island Armory STK100, the striker-fired 9mm that stands out for its aluminum grip frame, an unusual choice in a market dominated by polymer that gives the pistol noticeably different weight and recoil characteristics. Running factory-correct magazines is the single easiest way to avoid feeding problems, and having spares on hand means less time reloading at the range and more time shooting. This is a ten-round version, which also makes it the right choice for shooters in capacity-restricted jurisdictions. Black finish and standard baseplate.
